While most diamonds in the world are mined from natural sources, technological advances are now making synthetic diamonds a viable alternative. On this program, Ulrich Boser discussed the world of synthetic diamonds. Topics: science, diamonds, carbon, synthesis Source: Groks Science Radio Show Podcast
Industrial processes produce carbon dioxide emissions at a staggering rate. Recycling carbon dioxide into fuel sources may help recapture some of these emissions into a useful form. On this program, Byron Elton discussed carbon recycling technology. Topics: science, environment, carbon recycling, carbon dioxide, greenhouse gas, groks Source: Groks Science Radio Show Podcast
What is the appropriate market mechanism for moving away from a fossil fuel economy? On this program, Lester Brown from the Earth Policy Institute discussed how carbon taxes could better represent the true cost of energy. Topics: science, sustainability, environment, carbon tax Source: Groks Science Radio Show Podcast
Scientists estimate that one-third of today's increase in greenhouse gas emissions come from changes in the land-use. One way to sequester the carbon emissions is plant more trees but are other crops out there better? On this program, special correspondent Terry Yen talks about the promise of anthropogenic peat. Topics: science, greenhouse gas emissions, peat, carbon Source: Groks Science Radio Show Podcast
Bulk carbon comes in many different forms from pencil lead to diamonds. At the nanoscopic level, the properties become even more exotic. On this program, Hari Manoharan talks about what happens when nanostructures of carbon are combined. Topics: buckyballs, carbon, graphene, diamonds, nanotechnology, diodes, LED
How do aerosols, or tiny particles, affect the climate? Do they block solar radiation or warm the planet? On this program, John Moore discusses the science of dust in the sky and how we could mitigate the effects of hurricanes. Topics: aerosols, atmospheric chemistry, carbon, NOX, SOX, geoengineering, hurricanes
Less than a half a million African elephants live in the wild and more than 25,000 of those are poached every year. They are poached for their ivory even though African ivory collected after 1989 is generally illegal. One reason such robust poaching persists is that, until recently, there has been no way to determine when ivory was collected. Dr. Kevin Uno joins us to discuss his recent PNAS article detailing a test that closes this loophole. In the process, we discuss carbon, ecology,... Topics: Groks, elephants, carbon, isotopes, C13, C14, C12, ecology, conservation, Kevin Uno, Lamont...
The international negotiations for addressing climate change has been fraught with rancor but the COP-21 meeting in Paris last month marks a turning point. On this program, David Victor discusses the Paris Agreement, the Intended Nationally Determined Contributions, and what needs to be done to truly address the global climate problem. Topics: climate change, mitigation, greenhouse gases, energy, nuclear, CCS, carbon, France, INDC Source: Groks Science Radio Show Podcast
